PEB 3331 HT V2.1

Telecom Overview

The Infineon PEB 3331 HT V2.1 is a VINETIC®-1CPE VoIP processor designed for Customer Premises Equipment (CPE). It integrates a 1-channel analog CODEC, VoIP DSP, and SLIC interfaces within a PG-TQFP-64 package. The device supports up to two simultaneous VoIP channels using G.723.1 or G.729A/B/E coders, alongside G.711, G.726 ADPCM, iLBC, and T.38 Fax Relay. It features an adaptive jitter buffer, window-based line echo cancellation (WLEC) up to 128 ms, DTMF/CID processing, and a PCM interface for external ISDN or FXO connectivity.

Telecom Feature Summary

• Integrates a single-channel analog CODEC with dedicated interfaces for SLIC-DC V1.2 and SLIC-E V2.1 Subscriber Line Interface Circuits.
• Provides flexible voice coding capabilities supporting multiple standards including G.729, G.723.1, G.711, and T.38 Fax Relay protocols.
• Includes advanced signal processing functions such as adaptive jitter buffering, window-based line echo cancellation, and caller ID handling.

Telecom Applications

• VoIP home gateways and broadband IADs
• Small Office/Home Office (SOHO) IP PBX systems
• WiMAX and xPON network terminals with voice services

Telecom Procurement Notes

Verify component authenticity through authorized Infineon distribution channels. Confirm the specific revision level matches system requirements. Check for end-of-life status and availability of long-term supply agreements. Ensure compatibility with existing firmware drivers and hardware schematics before procurement.

Telecom Selection Notes

Select this model when a single analog telephone interface is required alongside robust VoIP processing. Compare against the PEF 3331 variant if RoHS compliance is mandatory. Consider the PEB 3332 version if dual-channel FXS support is needed. Evaluate the VINETIC-ATA series for cost-sensitive applications requiring reduced channel capacity.

Telecom Part Context

This component belongs to the VINETIC®-CPE family, which offers scalable VoIP solutions for CPE markets. It shares software compatibility with other family members like the VINETIC-PLUS and VINETIC-ATA series. The device serves as a central processing unit for converting analog voice signals into packetized RTP streams for network transmission.

Telecom Replacement Considerations

The PEF 3331 HT V2.1 is a direct RoHS-compliant alternative to the PEB 3331 HT V2.1. For dual-channel requirements, consider the PEB 3332 HT V2.1. Verify pinout and software driver compatibility when substituting with other VINETIC-CPE family members.
